RATIONALE: The calcaneal fracture without broken lateral wall is rare and the open anatomic reduction and internal fixation (ORIF) is necessary when the subtalar joint articular surface is broken and collapsed. PATIENT CONCERNS: A 45-year-old male was admitted to our department with complaints of heel pain and swelling after falling down from 1-m-high stone. He was unable to bear weight on his right foot. DIAGNOSES: Imaging studies confirmed that it was a sanders type IIIAB calcaneal fracture without broken lateral wall and the middle part of the posterior calcaneal articular facet collapsed...

INTRODUCTION: Hip arthroscopy has become a standard procedure in the treatment of hip joint pain not related to osteoarthritis or dysplasia in the young and active patient. There has been increasing focus on the contribution of the hip capsule to function and on stability following hip arthroscopy. It has been suggested that capsular closure after hip arthroscopy may prevent microinstability and macroinstability of the hip joint and reduce revision rate. However, it remains unknown whether capsular closure should be performed as a standard procedure when performing hip arthroscopies, especially in patients without additional risk factors for instability such as hypermobility or dysplasia of the hip...

We tested whether inhibiting mechanically responsive articular chondrocyte mitochondria after severe traumatic injury and preventing oxidative damage represent a viable paradigm for posttraumatic osteoarthritis (PTOA) prevention. We used a porcine hock intra-articular fracture (IAF) model well suited to human-like surgical techniques and with excellent anatomic similarities to human ankles. After IAF, amobarbital or N -acetylcysteine (NAC) was injected to inhibit chondrocyte electron transport or downstream oxidative stress, respectively...

PURPOSE: To compare fixed- or variable-angle locking screws in calcaneal fracture plates using a sawbones biomechanical model. METHODS: Intra-articular calcaneal fractures were created in synthetic bones. Reduction and stabilization was performed with three different plates. In Group A, a fixed-angle locking plate was used with screws fastened perpendicularly to the plate (3.5 LCP, DePuySynthes). In Groups B and C (2.7 VA-LCP, DePuySynthes and 3.5 Aptus, Medartis, respectively), fracture fixation was performed using variable-angle locking plates...

BACKGROUND: Fractures of the distal radius are the most common fractures in the upper extremity, and their incidence is increasing with the aging of the population. Despite anatomical reduction of the bones, many patients complain of residual pain. A reason for this may be ligament injury not addressed during surgery or conservative treatment. Radiographic measurements may allow assessment of ligament integrity but they may be population specific and differ among races. OBJECTIVES: To assess radiographic wrist measurements in an Israeli population and to compare them to existing values...

INTRODUCTION: Osteosarcoma (OS) is a primary bone malignancy, characterized by spindle cells producing osteoid. The objective of this study is to describe the magnetic resonance imaging (MRI) features of different OS subtypes, record their attenuation diffusion coefficient (ADC) values and to point to the relation of their pathologic base and their corresponding ADC value. PATIENTS AND METHODS: We performed a retrospective observational lesion-based analysis for 31 pathologically proven osteosarcoma subtypes: osteoblastic (n = 9), fibroblastic (n = 8), chondroblastic (n = 6), para-osteal (n = 3), periosteal (n = 1), telangiectatic (n = 2), small cell (n = 1) and extra-skeletal (n = 1)...

INTRODUCTION: For several extremity fractures differences in morphology, incidence rate and functional outcome were found when polytrauma patients were compared to patients with an isolated injury. This is not proven for distal radius fractures (DRF). Therefore, this study aimed to analyse fracture morphology in relation to energy transfer in both poly- and mono-trauma patients with a DRF. METHODS: This was a retrospective cohort study. All patients aged 16 years and older with a DRF were included...

Fractures of the scapular body that extend to involve the neck and glenoid articular surface with a large gap pose a significant problem for surgical exposure. Several surgical approaches for scapula fixation have been described, but all give limited exposure to the entire scapular body, neck and articular surface. Here, we describe our 'Reverse Judet' technique, with cadaveric dissections and discuss a clinical case. We believe this approach gives a wide exposure of the infraspinous scapular body, neck and glenoid articular surface while keeping away from vital neural structures...

PURPOSE: "Damage" is an engineering term defining a period between a state of material perfection and the onset of crack initiation. Clinically, it is a loss of fixation due to microstructural breakdown, indirectly measured as a reduction of stiffness of the bone-implant construct, normalized by the cross-sectional area and length of the bone. The purpose of this study was to characterize damage in a cadaver model of extra-articular distal radius fracture with dorsal comminution treated using 2-column volar distal radius plates...

Background: Primary benign and malignant tumors of the proximal fibula are not very common. Upper fibula being an expendable bone; the majority of the primary bone tumors at this site are usually treated with en bloc proximal fibulectomy. There is scarce literature on functional results, difficulties faced during dissection when to preserve or sacrifice common peroneal nerve and importance of lateral collateral ligament repair after proximal fibulectomy. The present study attempts at assessing these variables...

The extensor mechanism of the knee-consisting of the four muscles of the quadriceps, the quadriceps tendon, the patella, and the patellar ligament-is essential for lower extremity function during both standing and ambulation. The presence of articular cartilage and growing physes in the pediatric knee, coupled with the generation of significant tensile force, creates an opportunity for pathology unique to the pediatric population.Tibial tubercle fractures and patella injuries are quite rare, and even pediatric-trained orthopaedic surgeons may not be exposed to these injuries on a regular basis...

INTRODUCTION: Cuboid fractures are very rare. Hence, their treatment has not been standardized. Advances in imaging techniques, particularly three-dimensional computed tomography (3D CT), and the introduction of cuboid-specific plates has improved the care of these injuries. The aim of this study was to determine the radiological and clinical outcomes of anatomical reconstruction of comminuted cuboid fractures with a locking plate. HYPOTHESIS: Fixation of comminuted cuboid fractures with a cuboid-specific locking plate leads to stable anatomical reduction and good functional outcomes...

Intra-articular fractures of the distal humerus are complex injuries that can considerably limit elbow function if not treated appropriately. Surgical management is indicated for most intra-articular distal humerus fractures with the goal of restoring elbow range of motion and function. Open reduction and internal fixation (ORIF) with plates and screws has been the preferred surgical option. Double plating is recommended for bicolumnar fractures and plates can be applied either parallel or orthogonal to each other...
